Because today's online environment for securing and maintaining high SERP ranks on Google is mired in such stiff competition, web designers must be ready to consider any possible advantage their websites can pursue to increase their chances of satisfying everyone within their audiences. As one example of this, designers should take into account all design standards pertaining to user accessibility so that any reader who might otherwise be interested in the brand is not turned away by some technical aspect clashing with their medical impairment. Just like how various software programs offer accessibility options to accommodate users with color blindness, websites can strive to make their text-based content more legible to users suffering from dyslexia.
It is commonly said that fonts without serifs result in less complex shapes that dyslexic readers can better visually distinguish, which is why they are commonly excluded from fonts explicitly designed for dyslexic readers. However, dyslexia affects readers in subtly different ways, and some may find reading mainstream sans-serif fonts like Arial easier in comparison. Since Arial is a commonly used font in general, it can be seen as an easy font to choose when trying to present text in a widely digestible form. In fact, many dyslexic readers will likely have acclimated to this font more closely because of how widespread its use is.
It is not possible for a website to land upon a font that can simultaneously accommodate every form of dyslexia affecting Internet readers. However, presenting a sans-serif font in a large font size will automatically result in more legible text to virtually everybody, and so will minimizing the presence of supplementary aspects like underlining and italics. It is helpful to readers in general that lines of text do not horizontally stretch excessively before wrapping around, and having softly colored backgrounds is less of a strain on the reader's eyes than defaulting to purely white backgrounds. Finally, readers in general — those with dyslexia included — are well served by having sitemaps arranged on page footers so that search functions are not the only way they can get to a desired subject.
